SPINNING-FRAME STOPPING MECHANISM.

Application filed April 8, 1924. Serial No. 705,070.

T 0 all whom it may concern:

Be it known that I, Roenn'r W. Gossn'r'r, a citizen of the United States of America, and a resident of Spartanburg, county of Spartanburg, and State of South Carolina, have invented certain new and useful Improvements in Spinning-Frame Stopping tvlechanisms, of which the following is a full and clear specification.

This invention is especially adapted for use in that type of spinning-frame in which a cop-builder mechanism automatically pulls a chain back and forth to lower and raise the ring-rail, the pulling on the chain serving to lower the rail and the paying-out of the chain serving to raise the rail through the medium of a series of weighted levers, a suitable ratchet-operated gain mechanism being employed to permit the ringrail to rise slightly higher upon each upward movement thereof, whereby the bobbins are progressively wound from their lower ends to their upper ends. The object of the pres ent invention is to provide a simple mechanism whereby when the ring-rail reaches a predetermined heightwith reference to the bobbins, the machine will be stopped, either by shifting the drive-belt onto the loose pulley or by opening the switch of an electric motor, as more fully hereinafter set forth.

In the drawing- Fig. 1 is a side elevation of so much of a well-known type of spinning-fran'ie as is necessary to illustrate my invention;

Fig. 2 is a perspective View of the latching mechanism] In the drawing annexed, 5 designates the usual rock-shaft for actuating the beltshifting fork 6 from the tight pulley to the loose pulley, and vice versa. The numeral 7 designates the usual builder-chain which at one end is attached to a quadrant 8 and at its other end is attached to the usual builder mechanism 9 which serves to tilt the quadrant toward the right when the chain is pulled-on, and to permit it to tilt toward the left when the chain is payed-out, the tilting toward the left being brought about by means of the rail-lifting mechanism embodying a weighted lever 10 which is provided with an arm 11 engaging under the adjacent lifter-rod 12 depending from the ring-rail 18. This mechanism is constructed as usual, and it will. be understood that the builder mechanism serves to reciprocate the ring-rail up and down a predetermined distance and at each reciprocation permit the rail to rise slightly higher than on the preceding stroke, to thereby cause the gain needed in building up the bobbin.

In my apparatus, I'u'tilize the rocking action of the lever 10 on its power, i. e., righthand stroke to bring about an actuation of the belt-shifter from the tight pulley to the loose pulley. I provide the quadrant with a pin 14; extending toward the right, so as to lie in the path of a depending bar 15 having a hook 16 at its lower end. This hook is pivotally connected to a bar 17 which is suspended by a chain 18. This chain 18 runs over a suitable idle pulley 19 and thence to a pulley 2O fastened to the rockshaft 5 of the belt-shifter mechanism. The finger let and the bar 15 are so arranged that during the reciprocations of the ringrail and its gradual rise to its final position, the finger 14: reciprocates up and down in the vertical plane of the hook. When the ring-rail nears the upper extremity of its movement, the finger 14 will strike the lower curved side of the hook and will swing the same laterally slightly; and then when the ring-rail reaches the predetermined limit of its upward movement, the pin 14!: will pass beyond the point of the hook and thus permit the hook to normally swing to a position under the pin; then the next downswing of the pin 14L- will engage the hook and thus pull down the chain. The pulling of the chain will obviously rotate the rock: shaft 5 of the belt-shifter mechanism and thus shift the belt to the loose pulley. It will be observed that with my arrangement, I do not depend on any springs, but utilize the source of power which runs the machine for shifting the belt. Obviously, instead of shifting the belt, I may arrange that the pull-chain 18 may be arranged to open the switch of the electric motor employed in dr ving the spi n ng-f me.

I/Vhat I claim as new is:

1. In a stopping mechanism for powerdriven spinning-frames, devices for cutting off the power, a builder mechanism and means actuated thereby on the power stroke of one of its elements for positively and directly actuating the power cut-off devices.

2. In combination with a power-driven spinning-frame, a builder mechanism for reciprocating the ring-rail and gradually elevating it, said builder mechanism embodying a lifting-lever actuated in one direction by a power-actuated chain and actuated in the other direction by a Weight and mechanism positively and directly actuated from the lifting-lever for cutting oil? the source of power for driving the spinning-frame.

3. In combination with a power-driven spinning-frame, a builder mechanism for reciprocating the ringrail and gradually elevating it, said builder mechanism embodying a lifting-lever actuated in one direction by a power-actuated chain and ac tuated in the other direction by a weight, and mechanism positively and directly actuated from the lifting-lever on its raillowering stroke for cutting off the source of power for driving the spinning-frame.

4. In combination with a power-driven spinning-frame, a builder mechanism for reciprocating the ring-rail and gradually elevating it, said builder mechanism embodying a lifting-lever actuated in one direction by a power-actuated chain and actuated in the other direction by a weight, and mechanism actuated from the lifting lever on its rail lowering stroke for cutting off the source of power for driving the spinning-frame, said mechanism embodying a finger carried by the lifting-lever, a pendent latch-hook adapted to be interlocked with the finger when the ring-rail reaches the limit of its predetermined movement,

and an actuating chain connected to said pendent latch-hook.

In testimony whereof I hereunto affix my signature.

ROBERT W. GOSSETT.
